"We naturally express our most serious concern about the use of force and the death of civilians," Russian Foreign Minister Sergei Lavrov was quoted as saying on the sidelines of a meeting of Group of Eight foreign ministers in Italy.
"We count on all questions which have arisen in the context of the elections being resolved in accordance with democratic procedures," Lavrov said.
Russia and China earlier this month congratulated Iranian President Mahmoud Ahmadinejad on his controversial re-election as he attended a summit in Russia.
Official results handed Ahmadinejad a landslide victory while defeated candidate Mirhossein Mousavi has said the vote was rigged.
Group of Eight powers deplored the post-election violence in Iran on Friday and called on Tehran to resolve the crisis soon through democratic dialogue.
